There is a "weightingFilter" function that converts given signal to weighted signal, for A,B,C audio filters. Can we include our own filter in the function ?

The weighting filter I have has 44 frequencies and is taken from ISO-2631 standard. And my signal has 20 samples in discrete time between 0 to 10secs. The goal is to get weighted signal as output. If we can not include our filter in the MATLAB function, then how do we calculate weighted signal ?

Taking a short signal with low time resolution and using an interpolating spline on it will not give you something that can be adequately analyzed at 44 frequencies. A sample rate of 2 Hz would require that the signal duration be... not sure, a couple of days?? in order to be able to resolve the frequencies. And that is assuming repeated signal.
You are probably going to have to increase your sampling rate
